PLOW,

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed July 1, 1905. 'Serial No. 267,942.

T0 aZZ whom it may concern:

Be it known that I, J AOOB OoLLINs, a citizen of the United States, and a resident of Dockery, in the county of Sunflower and State of Mississippi, have invented a new and Improved Plow, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide a simple, strong, and economic plow especially adapted for opening new ground, but which may be successfully employed in all work adapted to the plow, and particularly to provide adjusting mediums for a knifecolter whereby said colter may be given vertical adjustment or adjustment to or from the point of the share, which adjusting mediums can be quickly and conveniently operated and are of such construction that a guide is provided for the colter between its ends and the colter is held at a side of the beam, the adjustment of the colter being accomplished by simply sliding the adjusting mediums to and from the heel of the beam.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved plow. Fig. 2 is a vertical longitudinal section through the rear portion of the plow; and Fig. 3 is a transverse section through the beam, the section being taken practically on the line 3 3 of Fig. 2.

A represents the beam of the plow and is made quite strong and solid. It is provided at its rear with the conventional handles 10, and adjacent to its rear end the beam is provided with an offset 11 upon its upper face, as is shown in Figs. 1 and 2.

B represents the stock, which is secured to the rear end of the beam in any approved manner and is stayed by means of a bracebolt 12, extending from the beam forward of the offset 11 andthrough the said stock, as is also shown in Figs. 1 and 2.

The share 13, which is of the moldboard type, is made longer than usual and simply rests upon the forward face of the stock and The said share at its left-hand longitudinal edge is provided with a rearwardly-extending flange 14, Which fits snugly against the side face of the stock B, so that the flange 14 serves to steady the share and likewise serves to strengthen the stock, as said flange is not countersunk in the stock, but simply has bearing thereon.

A strap 15 is longitudinally secured to the left-hand side of the beam A, said strap being preferably made to extend around the front of the said beam, and at a point near the center of the beam A the strap 15 is bent downward and rearward in direction of the share 13, as is shown in Fig. 1, and this downwardly-extending terminal 15 of the strap 15 is provided at the left-hand side of its rear end with a guide 16, which is in the nature of a U-bolt having suitable nuts thereon.

O represents a knife-colter, which may be of any approved type, and D represents the adjusting mechanism for said colter. This adjusting mechanism consists of two opposing plates 17 and 17, adapted to slide upon opposite sides of the beam A at the rear of the offset 11, and said plates 17 and 17 are provided with upper and lower inwardly-extending flanges 18 and 18, which flanges engage, respectively, with the upper and lower faces of the beam A, as is best shown in Fig. 3.

The adjusting-plates 17 and 17 are provided with lower alining apertures 19 and upper alining apertures 20, and the beam A is provided with an upper longitudinal slot 21, in registry with the upper apertures 20 in the adjusting-plates, and with a lower longitudinal slot 22, in registry with the lower apertures 19 in said adjusting-plates, as best shown in Fig. 2.

A U-bolt 23 is employed in connection with the adjusting-plates, and the members of the said U-bolt are passed through the left-hand side of the beam, respectively through the upper apertures 20 in the plates, the upper slot 21 in the beam, the lower apertures 19 in the plates, and the lower slot 22, as is shown in Figs. 2 and 3. The members of the said U- bolt 23 are provided with nuts at their righthand ends. The shank of the knife-colter O is passed through the guide 16 on the strap 15 and then up through the U-bolt 23 to an engagement with the outer face of the righthand adjusting-plate 17. The knifecolter plate 17,

When it is desired to adjust the knifecolter C away from the point of the share 13, the nuts on the U-bolt 23 areloosened and the adjusting-plates and the said U-bolt are slid bodily of the said beam A in direction of its rear as far as may be required, thus carrying the knife-colter G to the dotted position shown in Fig. 1, for example. When the adjustment of the knife-colter is to be made toward the point of the plow, the adjusting device D is simply slid the required distance toward the forward end of the plowbeam. In both cases after the adjustment has been made the nuts of the U-bolt are tightened, and likewise the nuts on the guide 16, if such nuts had been loosened. If it is necessary to adjust the knife-colter vertically, the nuts on the guide 16 and the nuts on the U-bolt 23 are loosened and the shank of said colter is carried upward or downward, as may be required, after which adjustment the nuts are properly tightened.

By reference to Fig. 2 it will be observed that the slots 21 and 22 are parallel and that the forward end of the slot 22 is in vertical alinement with the rear end of the slot 21, thus permitting a wide range of adjustment of the adjusting device D.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a plow, the combination with abeam, a stock and share, the said beam being provided with longitudinal parallel slots extending through from side to side, one located above the other, the forward end of one slot being beneath the rear end of the other slot, of plates mounted to slide on opposite sides of the said beam at its slotted portion, said plates being provided with apertures which register with the said slots and a U-bolt provided with suitable nuts, the members of which bolt are passed through the said slots in the beam and the registering apertures in the said plates, and a knife-colter the shank of which is passed through the bow portion of the said U-bolt to an engagement with the outer face of one of said plates, for the purpose described.

2. In a plow, the combination with a beam,

a stock secured to the said beam, a strap secured longitudinally of the beam, having its rear end extending downward and rearward, and a guide carried by the rear end portion of the said strap, the said beam being provided with parallel slots extending through from side to side, one slot being above the other and the inner ends of the slots being in substantially vertical alinement, of an adj usting device comprising opposing plates having upper and lower inwardly extending flanges, which plates are adapted to slide on the slotted portion of said beam, each plate being provided with apertures in registry with the slots in the beam, a U-bolt the members of which are passed through the apertures in the said plates and the corresponding slots in the said beam, the ends of said members being provided with nuts, and a knifecolter the shank of which extends up through the guide on the said strap and through the U-bolt between its arched end and the outer end of the adjacent sliding plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
